How cannabis affects brain development during adolescence

Official title: Impact of Cannabis on Prefrontal Maturation

Funded at University of Illinois at Chicago · NIH-10930821 · Data updated 2026-11-12

This study is looking at how using cannabis during the teenage years might affect the development of an important part of the brain called the prefrontal cortex, which helps with thinking and managing emotions, so we can better understand the potential long-term effects on young people's mental health.

Who could benefit from this research

Could help

Ideal candidates for this research are adolescents aged 12-20 who have used cannabis or are at risk of cannabis use.

Less likely to help

Patients who are not adolescents or who have not been exposed to cannabis may not benefit from this research.

What this research studies

This research investigates the impact of cannabis exposure on the maturation of the prefrontal cortex (PFC) in adolescents. It aims to understand how cannabis use during this critical developmental period may lead to cognitive and emotional regulation deficits later in life. The study will focus on the neurobiological processes that are sensitive to cannabis exposure, particularly the balance of excitatory and inhibitory signals in the brain. By examining these mechanisms, the research seeks to uncover the specific ways in which cannabis affects brain development and function.

Why it matters

Potential benefit: If successful, this research could lead to better understanding and prevention of cognitive and emotional issues related to adolescent cannabis use.

How similar studies have gone: Previous studies have indicated that cannabis exposure during adolescence can disrupt brain development, suggesting that this research builds on established findings.
